I had been hunting for an answer to the elusive question of how do I reset array keys in PHP.  I finally found the perfect (and thorough) answer here. There are 3 ways to reset array keys in PHP.  All of these solutions work with numerically indexed arrays only. To recap:

PHP Function: array_values()

Show Plain Text
  1. $reset_array_keys = array_values($numerically_indexed_array);

PHP Function: array_merge()

Show Plain Text
  1. $reset_array_keys = array_merge($numerically_indexed_array);

Foreach loop (aka kindergarten method)

This was the way I was going to reset the keys, but couldn't bring myself to doing it, as the name above implies.

Show Plain Text
  1. $reset_array_keys = array();
  2. foreach($numerically_indexed_array as $value) {
  3.     $reset_array_keys[] = $value;
  4. }

Cheers,
